（一）Hbase_ Centos7伪分布式环境配置

一．修改主机名

vim /etc/hosts

修改为hadoop-standalone   //主机名可以自定义

yum -y install net-tools ntp lrzsz vim

 

二．配置环境变量：

vim ~/.bashrc

将下面代码复制到里面保存退出

export JAVA_HOME=/usr/lib/jvm/jre-1.8.0

export PATH=$PATH:$JAVA_HOME/bin

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

#zookeeper

export ZOOKEEPER_HOME=$/opt/zookeeper

export PATH=$PATH:$ZOOKEEPER_HOME/bin

#hadoop

export HADOOP_HOME=/opt/hadoop

export HADOOP_PREFIX=$HADOOP_HOME

export HADOOP_MAPRED_HOME=$HADOOP_HOME

export HADOOP_COMMON_HOME=$HADOOP_HOME

export HADOOP_HDFS_HOME=$HADOOP_HOME

export YARN_HOME=$HADOOP_HOME

export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native

export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin

export HADOOP_INSTALL=$HADOOP_HOME

#hbase

export HBASE_HOME=/opt/hbase

export PATH=$PATH:$HBASE_HOME/bin

 

三．远程授权设置：

RSAAuthentication yes

ssh-keygen -t rsa

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

systemctl restart sshd

 

四．配置zookeeper：

cd /opt/zookeeper/conf/

cp zoo_sample.cfg zoo.cfg

五．Hadoop配置

#core-site.xml

<property>

         <name>hadoop.tmp.dir</name>

         <value>/opt/hadoop/tmp</value>

</property>

<property>

         <name>fs.defaultFS</name>

         <value>hdfs://hadoop-standalone:8020</value>

</property>

 

 

#hdfs-site.xml

<property>

         <name>dfs.replication</name>

         <value>1</value>

</property>

<property>

         <name>dfs.namenode.name.dir</name>

         <value>file:///hdfs/name</value>/opt/hadoop/data

</property>

<property>

         <name>dfs.datanode.data.dir</name>

         <value>file:///hdfs/data</value>/opt/hadoop/temp

</property>

<property>

         <name>dfs.permissions</name>

         <value>false</value>

</property>

 

六．Hbase配置

#hbsae-site.xml

<property>

         <name>hbase.cluster.distributed</name>

         <value>true</value>

</property>

<property>

         <name>hbase.rootdir</name>

         <value>hdfs://hadoop-standalone:8020/hbase</value>

</property>

<property>

         <name>hbase.zookeeper.quorum</name>

         <value>hadoop-standalone</value>

</property>

<property>

         <name>hbase.zookeeper.property.dataDir</name>

         <value>/opt/zookeeper/data</value>

</property>

<property>

         <name>hbase.procedure.store.wal.use.hsync</name>

         <value>true</value>

</property>

<property>

         <name>hbase.unsafe.stream.capability.enforce</name>

         <value>false</value>

</property>

 

七．启动服务

启动zookeeper：zkServer.sh start

启动hadoop的dfs：start-dfs.sh

启动hbase：start-hbase.sh

八．验证服务

查看服务是否启动完整：jps

5122 Jps

5028 HRegionServer

4917 HMaster

4183 QuorumPeerMain

4343 NameNode

4472 DataNode

4638 SecondaryNameNode

有以上七个服务表示环境搭建完成

 

九．验证hbase数据库：(自带的脚本命令)

->hbase shell

->status

显示数据库信息，表示安装完成
